A very cold night and a very hard frost – un-heated railway carriages concentrate cold and are really colder than the air outside. Lunch in the town. Left at 5.30 as a passenger to Rouen, Ward taking the trains – 12 nurses in my carriage. Nice nurses, very amiable, had only tea to give them. Arrived Darnétal 8 a.m. Havre 9 a.m.
